I've been in therapy for two years, and I still struggle with this, although it's getting better. So for me, I will have all these strong feelings during the week, be them about T or something else, and by the time I get to session I feel like they're nothing, like I made them up.
I recognise it as a defensive mechanism. I block these things subconsciously because I can't cope with expressing them to another person. I have discussed this with him and recently I have been pushing myself to express them anyway, which has led to frequent dissociation, but I am trying to weather the storm and continue because I feel if I can push myself a little at a time (as much as I can cope with) I will eventually be able to feel spontaneously.
I think the key to it all is communication between you and your therapist. If you can be honest about what is happening for you, change will occur, in time.
I also want to add that I feel for you regarding the hug issue. My first T refused to hug me when I asked and it was devastating. It sounds like she is willing to talk to you about it though, which is a good sign.
